How do you fix 1989 300e sunroof rattle
 

Victim 1989 W124, 300e, 3.0
Search but did not find any diy fix for rattling sunroof. Sunroof works well but rattles on rough road and going over speed bumps, it rattles in closed, open and tilt positions. All visible accessible screws are tight. Will not rattle if push up force is applied to sunroof. (No that is not what a radio is for) How do you access unit to check guide jaws/lifting arms/seals?

The sunroof guides have little felt-covered rubber feet that wear out and disintegrate. Replacing them is involved enough you should have a good diagram to guide you. Parts available from FastLane and others.

They call them 'guide jaws', and there are quite a few in the assembly.
